You can override the cursor instead of setting the cursor, like this:
您可以覆盖光标而不是设置光标，如下所示：
Mouse.OverrideCursor = Cursors.Wait;
Then when the operation is carried out, you can remove the override by setting it to null, like this:
然后在执行操作时，可以通过将其设置为 null 来删除覆盖，如下所示：
Mouse.OverrideCursor = null;

You are right. There is no Cursors.Defaultstatic property. But you can always set cursor of a control to nulland it will restore control's default cursor.
你是对的。没有Cursors.Default静态属性。但是您始终null可以将控件的光标设置为，它会恢复控件的默认光标。
// ...
btn.Cursor = Cursors.Wait;
// whatever... your operation.
btn.Cursor = null;
// now the Cursor is default again.

I think you need to store the current cursor in a variable before changing it to the Wait cursor and then set it to your cursor variable when you want to change it back.
我认为您需要在将当前游标更改为等待游标之前将其存储在一个变量中，然后在您想将其更改回来时将其设置为您的游标变量。
